The camera technology is irrelevant (WRT to taking of the photo). It's the limitations of the radar that are the issue... ie. beam width, the cross-sectional area of the vehicles alongside or even out of frame.

There's a reason why they were defined under the legislation as scientific instruments, so they wouldn't have to prove they were working correctly, YOU would have to prove they weren't.

If you're certain you weren't speeding, the first step is usually to request calibration logs/results. Friend got off when they requested these under FOI, but the police failed to produce them. As far as arguing the physics, it will cost you more to get an expert witness to appear on your behalf than the fine. Even though common sense says two vehicles in frame and yours not the central one should create sufficient doubt, it will still be up to you to prove the reading was erroneous.
